This invention relates to'wire-stitching ma- '45 chines in which wire isfed and severed into suitable lengths for staples and the staples 5formed and driven through book or other material which it is desired tofasten together and clinched in place.

The objects of my invention are to provide a new and improved feedmechanism for feed Fig. 12 is a detail,

ing the wire, to provide novel feed-adj usting devices, to lprovidenovel means for forming the legs of the staples of uniform length, toprovide novel wire-straightening devices, and to generally improvemachines of the character referred to.

To accomplish these objects my linvention consists in the combinationsof devices hereinafter described, and pointed out in the 6o claims. Y

In the drawings, 1.7 indicates the supporting-pillar of the machine,from which extend two goose-neck supports 18 and 19.

2O (seeFig. 8) indicates a driving-shaft, 65 which is journaled in thegoose-neck 19 and carries a driving-pulley 21 upon its outer end.

22 indicates a back plate, which is secured upon the projecting end ofthe goose-neck 19 and is provided with a suitable opening 7o throughwhich the driving-shaft 2O passes,

and with side pieces 2.3, forming supports ,upon which aglass plate 24may be secured, protecting the parts, as is best shown in Fig. 2.

25 indicates a cam, which is keyed upon 75 the outer end of thedriving-shaft 20, resting with its back against the surface of the backplate 22. The cam 25 has an outer cam-surface `2.6,which operates tomove the Wire-feeding'device, as hereinafter described. It is 8c alsoprovided with a cam-groove 27, which is adapted to operate the stapleformer and driver, as hereinafter described.

28 indicates a spool, which is rotatably mounted upon a bracket29,.secured to the goose-neck 19.

30V indicates a pin, which'is mounted horizontally on the top ofthe-'bracket 29 above the spool. p

Slindicates a band of leather or other suit- 9o able material the end ofwhich is secured upon the pin 30. The belt 31 passes around the spool asuitable distanceand is provided with'anopening 32, through which thewire' may pass, as is best shownfin Fig;- 16.

33 indicates a spiral spring of suitable tension connecting the free endof the belt 3l with the pin 30, as is best shown in Fig. V16, andoperating to cause ,thev belt- 31 to `lofe'ar with proper force uponvthe spool 28 as it ro- Io tates. 2

34 indicates a hollow arm secured to the back plate 22. 35 indicates asliding rod moving horizontally in and out in said hollow arm 34, andcarrying upon its outer end a curved tension-tube 36. A spiral springoperates to push the rod 35, and with it the tension-tube 36, outward,so as to cause the proper degree of tension upon the wire which passesfrom the spool 28 through the tension-tube 36; but as these devices areold and well known it is not necessary to describe them inv detail.

37 indicates a feed-lever, which is pivotally mounted upon the backplate 22 upon a stud 38, which carries at its upper end a roller 39,which is adapted to bear upon the outer surface of the cam 25. Aspiralspring mounted upon the stud 38 operates to force the upper end of thefeed-lever 37, and with it the roller 39, toward the cam 25; but as suchspring and its method of attachment and operation are old and well knownin this class of machines I have not shown it in the drawings, and itwill not be necessary to describe itin detail. The lower end of thefeed-lever 37 is provided with a slot 40, adapted to engage with a pinupon the sliding feeder and move the same back and forth, as hereinafterdescribed.

41 indicates a feed-adjuster, which is provided with a projecting block42 upon its rear surface, adapted to slide horizontally in a slot 43 inthe back plate 22, as is best shown in Fig. 4.

44 indicates a back piece, which is bolted to the back of the block 42and adapted to bear against the back surface of the back plate 22 aboveand below the slot 43, so as to hold the feed-adjuster upon the backplate.

45 indicates a rod, which is secured to the back piece 44 and projectshorizontally a suitable distance beyond the edge of the back plate andis screw-threaded upon its outer end.

46 indicates a screw-threaded tube rotatably mounted in au ear 47,secured to the back plate 22, as is best shown in Fig. 4. The tube 46 isprovided with a thumb-wheel 48 upon its outer end, whereby the tube 46may be turned. As the thumb-wheel48 is turned the rod 45 will be movedforward or backward, as the case may be, carrying with it and movinghorizontally upon the back plate 22 the feedadjuster 4l, as is bestshown in Fig. 4. The feed-adjuster 41 is provided in front with a recess49, in which the lower end of the feed-lever 37 moves.

50 indicates parallel rods secured to the feed-adjuster near the frontof the recess 49, one near its top and the other near the bottom andpassing across from side to side.

51 indicates a feeder which is slidingly mounted upon the rods 50, whichpass through suitable openings in the feeder 51.

52 (see Fig. 4) is a roller mounted upon the back of the feeder 51 andadapted to engage with the slot 40 in the lower vend of the feed-lever37. As the feed-lever 37 is Vibrated by the action of the cam the feeder51 is carried horizontally backward and forward upon the rods 50. Thecam 25 is driven in the usual manner in these machines, and as itsconstruction and operation are the same as are found in machines of thischaracter and are well known it is unnecessary to describe them morefully here.

53 indicates a feed-adjusting screw, which passes through a threadedopening in the projection 54 of the feed-adjuster 4l. By screwing thefeed-adjusting screw 53 in or out the backward motion vof the lower partof the feedlever 37 will be limited by the feed-lever 37 coming againsttheend of the feed-adj usting screw 53, thereby regulating the distancewhich the feeder 51 is carried backward in tbe feed-adjuster 41.

55 indicates a gage, which is engraved or marked in any suitable mannerupon the surface of the recessed portion 49 of the feedadjuster 41.

5b' indicates a point which is formed upon or secured to the lower endof the feed-lever 37 and which passes across the surface of the gage 55.

57 indicates a bar, which is secured to the end of the feed-adjuster andpasses horizontally outward through a recess in the slidebox hereinafterdescribed. The outer end of the bar 57 is provided with a number ofvertical marks, which are adjusted so as to form a gage by which themovement of the-feedadjuster 41 may be regulated to the desired amountwhen moved-backward or forward by the action of the thumb-wheel 48, ashereinbefore described. The gage-marks upon the end of the bar 57 are soplaced as to conform with the divisions upon the gage 55, so that whenthe feed-adjuster is moved to a position indicated by any one of thenumbers upon the gage at the end of the bar 57 the point 56 upon thefeed-lever 37 may be adjusted by the feed-adjusting screw 53 upon acorrespending number of the gage 55, and when the machine is operatedthe legs or arms of the staple will be of the same length.

58 indicates a shoulder, which is preferably formed separate from andsecured to the lower end of the feeder 5l, and is provided at each endwith upwardly-projecting ears 59, which are pierced for the passage ofthe wire, so that the wire passing through them will rest upon the uppersurface of the shoulder 58. I have shown the shoulder 58 as formedseparately from and securedto the lower end of the feeder 51, and thatis the way in which I prefer to make it; but it is obvious that it mightbe formed integral withI it.

6() indicates a check-pawl, which is pivoted at its upper end upon theouter surface of the feeder 5l and is provided at its lower end with aprojecting pin 6l.

62 indicates a spring, which is secured at its upper end to the pivotupon which the checkpawl 6,0 turns, and at its lower end bears IOO IIO

upon the pin 6l, so as to force thelower end of the check-pawl downwardtoward the upper surface of the shoulder 58.

63 indicates a wire-gripper, which is piv-v otally mounted upon thelower` end of the check-pawl 60 and has its edge serrated to enable itto grip the wire. The operation of the check-pawl is such that when thefeeder 51 is moved by the action of the feed-lever 37 toward the stapleforming and driving mechanism hereinafter described the wiregrippercoming in contact with the surface of the wire will tend to press itagainst the shoulder 58 and hold it firmly in position, preventing thewire from slipping upon the shoulder and forcing it forward as thefeeder moves. When the feeder is moved in the opposite direction by theaction of the feed-lever, the gripper will be freed by the backwardmotion of the feeder from the surface of the wire, permitting it toslide upon the wire.

64 indicates a shoulder similarin form and construction to the shoulder58 and secured upon the outer end of the feed-adjuster 41,

as is best shown in Figs. 3 and 5.

65 indicates a check-pawl similar in construction and operation to thecheck-pawl 60 and having a wire-gripper 66 pivotally mounted on its endsimilar in form, construction,and operation to the wire-gripper 63, anda spring 67 operating to force the lower end of the check-pawl downwardagainst the shoulder 64. The operation of the pawl 65 is such that whenthe Wire is pulled through by the forward motion of the feeder 51 thelower end of the pawl will be raised, permitting the wire to slidethrough. When the feeder 5l is moved backward in the opposite direction,the lower end of the pawl 65 is forced downward upon the wire, holdingit against the shoulder 64 andpreventing it from moving backward as thefeeder is moved backward. The wire, after passing through the feeder 51,passes through a suitable opening 68, horizontally pierced through theinner end of the feedadjuster 41.

69 indicates a wire-cutter, which is mounted so as to slide verticallyin suitable grooves on the inner end of the feed-adjuster 41, as is bestshown in Fig. 11. The inner end of the feed-adjuster 41 is provided witha vertical slot 70, as is best shown in'Figs. 4 and 11, and thewire-cutter 69 is pierced near its upper end with an opening 7l oppositesaid slot, through which opening 7l a pin secured to the staple-former,as hereinafter described, passes, reciprocating the cutter 69 with themotion of the staple-former, as hereinafter described, and operating tosever the wire as it passes out of the opening 68 close against the endof the feed-adjuster. As the wire is severed close to the end of thefeed-adjuster, as aforesaid, it is obvious that the farther thefeed-adjuster is moved away from the staple-forming devices by therotating of the thumb-wheel 48 the longer the staple will be. The lengthof the staple is thus adjusted to Vthe tension-tube 36.

which it is desired and is mounted upon the outer end of thefeed-adjuster 4l by means of a screw-lever 74 passing through the slot73 and screwed `into the end of the feed-adjuster41, as is best shown inFig. 4. The wire-straightener 72 is also provided with a suitableopening 75, through which the wire passes after leaving The object ofthe wirestraightener is to cause the wire, after passing vthrough thefeed-adjuster, to enter into the staple-forming apparatus hereinafterdescribed. If the wire after leaving the feedadjuster tends to benddownward, it may be caused to bend in the opposite direction by raisingthe free end of the straightener 72 a suitable distance, and if it tendsto bend upward the tendency may be corrected by mov- `ing the free endof the straightener downward a suitable distance. If thewire afterleaving the feed-adjuster tends to move in or out horizontally, it maybe corrected by moving the straightener 72 out or. in on the thumb-nut74 by means of the slot 73, anymovement of the wire-straightener in anydirection tending to cause the free end of the wire to bend in the samedirection after leaving the feed-adjuster.

ICO

76 indicates a slide-box, which is secured to the back of said platebeing cut away, as is shown in Fig. 10, to permit the movement of thestaple-former, hereinafter described. A

portion of one side of the slide-box, as is shown in Fig. 10, is cutaway to permit the movement of the knife-pin upon the stapleformer,hereinafter described.

79 indicates a guide, which I prefer to form separately from and secureto the lower end of the slide-box 76, as is shown in Figs. 10 and l2,for the purpose of forminga guide at the lower end of the groove 78.formed integral with the slide-box. The lower end of the slide-box 76 ispierced with an opening 80 for the passage through it of the lowerstaple-former, hereinafter described.

Y 81 indicates an upper staple-former, which is mounted and adapted toreciprocate in the groove 78 of the slide-box 76. The upperstaple-former 81 is provided at its upper end with a roller 82, which isrotatably mounted thereon and adapted to rest in and be operated by thecam-groove 27 in the cam 25, causing the staple-former to reciprocate upand down as the cam 25 is rotated. As this operation of the cam and thereciprocating of the staple-former are old and we ll known in this classof machines it is not necessary to de IOS lt may, of course, be

IZO

scribe them more fully in detail. The upper staple-former 81 is, ingeneral, of the same form and method of operation as the older andwell-known form of upper staple-formers in machines of this class, andis provided with a vertical groove at its front, in which a driver 83reciprocates, as hereinafter described. The upper staple-former 81 isprovided near its upper end with two recesses 84, one upon each side,and with a horizontally-projecting pin 86, (see Fig. 5,) adapted toengage with the opening 71 of the cutter 69 and reciprocate the cutteras the upper staple-former is reciprocated by the action of the cam. Thepin 86 projects into and works in the cut-away portion at the side ofthe slide-box nearest the feed-adjuster, as shown in Fig. 10.

87 indicates a staple-supporter, which is, in general, of the form andconstruction well known in this class of machines, except that at itsupper end it is provided with afork 88, which rests in the recesses 84in the upper staple-former 81, and is provided with a pin 89, projectinghorizontally forward at its upper portion, as is'best shown in Figs. 6and 7.

90 indicates a face-plate, which is removably secured to the outersurface of the slidebox 76, as is shown in Fig. 3 and indicated bydotted linesin Fig. 6. A central vertical opening is cut in theface-plate 90, and a spring 91 is mounted upon the face-plate 90 andpassing into said opening bears against the lower end of the supporter87, forcing it inv ward, as is best shown in Fig. 8.

114 indicates a spring, which is secured at its upper end upon a pin115, projecting downwardly from the pin 89 at its lower end in anopening 116 in the top of the face-plate 90. The spring operates to movethe staple-supporter 87 upward when freed from the upper shouldersformed by the recesses 84 as the upper staple-former moves upward, as isbest shown in Figs. 6 and 8.

83 indicates a driver, which is mounted in the groove in the front ofthe upper stapleformer 81, so as to slide freely vertically therein.

92 indicates a link, one end of which is pivoted eccentrically on thecam 25 and the other end pivotally secured to the upper end of thedriver 83, as is best shown in Figs. 3 and 5, causing the driver 83 toreciprocate vertically as the cam 25 is rotated. The driver 83, as isbest shown in Fig. 8, and the upper stapleformer 8l, as is best shown inFig. 6, are each provided with a small groove across the bottom, inwhich the wire rests when the devices are in operation. The lowerportion of the back of the upper staple-former 8l is cut away at thelower end of the recess therein, as is best shown in Fig. 8, enablingthe sides of the staple-former to straddle the lower stapleformer,hereinafter described, and the supporter 87 as the machine is operated.

93 indicates a box, which is secured to the back plate 22 and projectshorizontally backward therefrom.

' 94 indicates a lower staple-former, which passes through the opening80 in the slidebox 76 and into the box 93.

95 indicates a spiral spring surrounding the lower staple-former 94 inthe box 93 and bearing against a shoulder 96 of the said lowerstaple-former 94 and against the end of the box 93 and operating to pushthe lower stapleformer forward under the upper stapleformer and hammer,asis best shown in Fig. 8. The front end of the lower staple-former 94is rectangular in cross-section, as is best shown in Fig. 5, and isbeveled above and below, as is best shown in-Fig. 8. It is also providedwith a slot 97, extending-transversely across its end, as is best shownin Figs.v 5 and 8, of suitable size for the wire to pass through it.

98 indicates a saddle-frame, which is mounted upon the upper end of ablock 99, which is hollow, in order to permit the passage through it ofparts hereinafter described.

100 (see Fig. 9) indicates a nut, which is secured to the end of thegoose-neck 18.

101 indicates a bolt, which is provided with a shoulder 102, that bearsagainst the lower portion of the block 99, as is best shown in Fig. 9.The bolt 101 passes through the nut 100 and is provided at its lower endwith a hand-wheel103, which operates as it is turned to raise or lowerthe block 99, carrying with it the saddle-frame 98. The bolt 101 ispierced to permit the passage through it of parts hereinafter described.A

104 indicates a table, which is divided longitudinally in two parts,which are hinged together, as is best shown in Figs. 1 and 3.

105 indicatesbraces, which are hinged below the table 104. The braces105 are adapted to rest in grooves 106 at the bottom of the saddle-frame98 and operate when in position to hold up the two parts of the table104, so that it may form one continuous level surface. When either ofthe braces 105 is free from the grooves 106 in the saddle-frame 98, thecorresponding part of the table will drop down, so as to rest upon thesaddle-frame 98. Either side or both sides of the table 104 may be sodropped as may be desirable from the nature of the work that it isdesired to stitch.

107 indicates a clincher-block, which is secured upon the upper end ofthe block 99, as is best shown in 'Figs 9 and 13.

108 indicates ciinchers, which are pivoted in said clincher-block 107 inan opening extending through said clincher-block, as is best shown inFigs. 13 and 14. The clinchers 108 `are of a U shape, and are pivotednear the bottom of one arm of the U, as is best shown in Fig. 13.

109 indicates a clincher-rod, which passes through the block 99 anddownward through the hollow bolt 101. The lower end is pivotallyconnected with a lever 110,which projects outward from the lowergoose-neck 18. The inner end of the lever extends within thesupporting-pillar 17 of the machine, and is moved up and down by anywell-known cam or other IOO reciprocating mechanism located within thepillar and connected with the driving-pulley 21 and operating, as thesaid lever 110 is vibrated, to reciprocate the clincherrod 109vertically. The lever 110 and the devices by which it is operated are ofthe ordinary and well-known form and construction in this class ofmachines, and it is therefore not necessary to describe them. The upperend of the clincher-rod 109 is provided with two lugs 111, which areelongated and adapted to loosely rest between the two arms of theclinchers 108 and operate to throw the upper arms of the clinchers upwhen the clincherr0d 109 is moved vertically upward and to bear againstthe lower Varm and throw the clinchers down when the clincher-rod 109 ismoved downward. The lugs 111 are elongated for the purpose of affordingacontinuous support and a firm bearing for the clinching-arms Y of theclinchers 108 when they are forced upward to clinch the staples, as isbest shown'in Fig. 13.

112 (see Fig. 9) indicates a jaw, which is secured upon the outer end ofthe goose-neck 18. 113 indicates a jaw, which is secured upon the lowerend of the block 99 immediately below the jaw 112 and moving with theblock 99. The jaws'1l2 and 113 are so adj usted that the distancebetween them may be the same as the distance betweenthe top of the tableand the operative parts of the staple forming and driving mechanism,thus forming a gage by which the height of the table may be adjusted tothe thickness `of the work which it is required to fasten. The work isplaced between the jaws 112 and 113, and by turning the hand-wheel103the block 99 is moved until the distance between the jaws 112 and 113corresponds to the thickness of the work. The work is then removed andthe staple will be adjusted at a suitable distance from the stapleforming and driving mechanism.

. 117 indicates atable, which is mounted upon `through the tension-tube.36, through the straightener 72, and through the openings in theshoulder 64 below the check-pawl 65. It is then passed through theopenings in the ears 59 of the shoulder 58 below the checkpawl 60 andthreaded through the opening 68 in the end of the feed-adjuster 41.Asthe machine is set in motion, the cam 25 revolving, bringing thecam-surface 26 in contact with the roller 39 upon the feed-lever 37,throws it outward, the inner end of the feed-lever.37 being carriedinward, carrying with it the feeder 51, thus carrying the wire forwardinto the slot 97 of the lower staple-former 94,

the feed-adjuster 41 having been previously adjusted according to thelength of the staple which it is desired to use. The portion of theouter cam-surface 26 between the stars on Figs. 3 and 5 is an arc of acircle whose center is the center of the driving-shaft 20. The upper endof the feed-lever having been thrown over to its greatest extent, theroller 39 bears upon the portion of the cam which is the arc of acircle, and the feed-lever is therefore retained in the position inwhich it has been thrown by the operation of the cam until it passesbeyond the end of that p0rtion which is the arc of a circle. As soon asthe feed-lever 37 has been operated to throw the wire into the groove ofthe lower stapleformer the cam-groove 27 begins to operate upon theroller 82 of the upper staple-former 81, moving itdownward with thedriver.4 As the staple-former begins to move downward, the pin 86engaging with the opening 71 of the cutter 69 brings the cutter 69downward upon the wire and severs it as the downward motio'n of theupper staple-former is continued. Its lower end straddling the lowerstaple-former 94 engages the wire in the groove at the bottom of theupper staple-former and bends the free ends of the wire downward overthe lower staple-former 94 into the form of a staple around the lowerend of the supporter 87, which is carried downward as the upperstapleformer moves downward by the action of the upper shoulders of therecesses 84 coming in contact with the fork 88. The portion of thegroove between letters a and b in Figs. 3 and 5 is an arc of a circle ofwhich the center is the axis of the driving-shaft 20. As the cam rotatesso that the roller 82 passes beyond the point a the upper stapleformeris held in the same position while the roller is passing upon theportion a b of the cam-groove 27. As the roller 82 comes to the point a,of the cam-groove 27 the link 92, as the cam 25 rotates, forces thedriver 83 still farther downward. As the driver comes against thebeveled surface of the lower staple-former 94 it forces it inward,leaving the staple which has been formed by the action of the upperstaple-former in its place between the sides of the upper stapleformer81 and the supporter 87 until the staple is freed from the lowerstaple-former, the upper staple former and supporter having been carrieddownward to their lowermost limit and resting upon the surface of thework. As the driver continues its downward course, the top of the stapleengages with the groove in the bottom of the driver, and the drivercoming in contact with the beveled top of the hinged portion of thesupporter 87 forces it outward as the driver descends, thus supportingthe sides of the staple as it is driven through the paper until thesupporter 87 is forced backward till the staple passes o from its pointand the staple is driven homeby the action of the driver. As the stapleis driven through the work, the points come in contact IOC IIO

' spring hereinbefore mentioned to its former position at the propertime to permit it to again grip the wire and push it under thestaple-former, as before. The bearing-surfaces of the cam-groove 27 andthe link 92 are so arranged as to return the upper staple former anddriver to their original positions after the staple is driven. As theclincher-rod 109 is moved downward after the staple is clinched, thelugs 111 coming in contact with the lower arms of the U-shaped clinchers108 return the clinchers to the original position shown in Fig. 13. Incase the wire passing through the machine bends so as not to enter thegroove in the lower staple-former the wire-straightener 72 is adjustedto cure the difficulty, as above described.

Before the machine is set in motion the parts are adjusted by means ofthe thumbwheel 48 and the feed-adjusting screw 53 until the point 56indicates the same position upon the gage as is indicated by the gageupon the arm 57, thus causing the two legs of the staple to be of thesame length.
